1. Network Madness
Caroline Haythornthwaite,The iSchool @ The University of British Columbia
Presented at the Learning Analytics Summer Institute, 2014, Boston, MA
A node, a relation, a network
2. Social Network Perspective
— Actors people, groups, organizations
— Tied by one or more relations
◦ Sometimes strongly tied
◦ Sometimes weakly tied
— Revealed as networks
— Analyzed and displayed as graphs
3. Network Questions
— Who learns from whom?
◦ Who talks to, gives help to,
collaborates with whom?
— What do they learn from each
other?
— Which media support which
kinds of learning?
— What outcomes do
these relations build?
◦ Access to resources
◦ Trust, mobility, equity, etc.
— What benefit accrues to the
network?
◦ social capital, shared
knowledge, shared resources
— How do resources flow in the
network

replied to or whose tweets are frequently retweeted

4. Strong and Weak Ties
StrongTies …
— Maintain more relations
— Have more frequent
interaction
— Include intimacy and self-disclosure
— Use more media
— Have higher reciprocity in
exchanges
Source of
• Freely given resources
• Feel obligation to share
! Questions
• How do you build strong learning ties,
online and through computer media?
• How do you motivate sharing in crowd-
and community-based initiatives?
• How do you build learning
communities?
5. Strong and Weak Ties
WeakTies …
— Engage in fewer, less intimate
exchanges
— Have more instrumental
exchanges
— Share fewer types of
information and support
— Use fewer media
Source of…
• New information, new resources
• Have little or no obligation to share
à Questions
• How do you bring peripheral actors
into the learning community?
• What is the right mix of tie strength to
sustain innovation and commitment?
6. Social Networks and Learning
Who to whom
— Who talks to, learns from, collaborates with
whom?
— What are the attributes of these actors?
What
— What do pairs talk about, do together?
— What does the network talk about, do
together?
Structure
— How does information circulate in a network?
— Who are the key actors who facilitate or
hinder information movement?
— Where is ‘expertise’ located?
Outcomes
— What identifiable relations, actor interactions,
information exchange binds the network?
— What social outcomes to these relations
build? trust, resources/services, mobility,
equality, opportunity, common knowledge
— What benefit resides in the network? -- social
capital
— Who talks to whom, about what, and via
which media?
— Who learns from whom?
— What relations constitute a learning tie? And/
or sustain a learning network?
— Which media support which kinds of
ties and relations
◦ How are ties, relations, networks maintained,
online and off, in the service of learning?
— What network structures emerge in the
service of learning?
— What impact do different strategies,
pedagogies, teaching and learning
practices have on network relations, ties
and structures?
◦ How do emergent structures align with
pedagogical, collaborative, cooperative – or even
isolationist – expectations and intentions?
◦ Whate learning outcomes result for individuals,
cliques, networks?
— What can we learn from network analyses
that inform design and design practice for
learning
7. Networks Are More Than Pictures
Networks show
— density
— actor centrality
— centralization
— cliques
— stars
— brokers
— isolates
— cliques
— structural holes
— path lengths
Network outcomes
— Resource flow
◦ inclusion and
exclusion
◦ early and late
access to
information
— Roles
◦ stars, gatekeepers,
entrepreneurs,
brokers,
translators
◦ information
suppliers, help
givers, social
support givers
— Social structures
◦ Social capital,
resilience
Collaborating on
class work
8. Who learns from whom, about what,
and via what means?
— Roles and Positions
◦ Technological guru, learner-
leaders, translators,
◦ Question askers and answerers
◦ Network stars and brokers
— Relations
◦ Information exchange, social
support, help giving
— Media
◦ Public and private
◦ Threaded (twitter) or
composite (wiki),
◦ Single (lecture hall) or multiple
(online/offline in various forms)
— Structures
◦ What structures emerge in the
in open learning environments?
◦ What is a ‘good’ structure?
◦ What impact do different
strategies, pedagogies, teaching
and learning practices have on
network relations, ties and
structures?
— Social Capital
◦ What benefits accrue to the
network?
— Design
◦ What can we learn from
network analyses that inform
design and design practice for
learning?

Network Evolution:
Email network over time Hidden Structures: External links; Internal core
Media Use: Chat, Discussion Board, Email
Media multiplexity
Classes and media form
latent tie structures on
which weak ties can build
into stronger ties
10. Discovery
— Who
◦ How do we identify
actors and their roles in
learning networks
— What
◦ What relations and ties
do people maintain? What
do they learn from each
other?
— Structure
◦ What network
connections are revealed
through learning ties?
— Moving toward
automated discovery
11. Node and tie discovery
Previous post is by Gabriel, Sam replies:
‘Nick,Ann, Gina, Gabriel:
I apologize for not backing this up with a good source,
but I know from reading about this topic that libraries…’
Previous posts by Gabriel, Sam, Gina, and Eva, then:
‘Gina, I owe you a cookie.This is exactly what I wanted to know.
I was already planning on taking 302 next semester,
and now I have something to look forward to!’
Post by Fred:
‘I wonder if that could be why other libraries
around the world have resisted changing –
it's too much work, and as Dan pointed out, too expensive.’

12. Nodes and ties in Twitter
— Who mentions
and/or replies to
whom
— Reveals a single
large component
with a moderate
periphery of
observers
Automated data collection: Who mentioned or
replied to whom, twitter network. Health care
learning community, #hcsmca (H&G, 2013)
13. Prestige and Influence
Green = social media health content providers
Blue = communicators, health related
Pink = advocacy
• Who is mentioned,
replied to most has
the greatest prestige
(In-degree) = node size
here
• Or, can see who
mentions or replies
to others most = the
greatest influence
(out-degree]
14. What do people learn from each other?
— Learning Relations
◦ What did you learn from the 5-8
others with whom you
communicate most frequently?
◦ Questionnaires and content
